The Argon Industria HMI 5C is an industrial-grade aluminum enclosure designed to house a Raspberry Pi 5 and the 5-inch variant of the Pi Touch Display 2, turning it into a compact Human Machine Interface (HMI) system for control panels, automation interfaces, and embedded display applications.
The enclosure supports VESA and panel mounting with a soft foam gasket design, with access to USB, Ethernet, HDMI, and GPIO ports via an internal IO board that reroutes connections (including converting micro-HDMI to full-size HDMI), and includes cable punch-outs for clean installation. The design allows HAT expansion (when the cooling column is removed), PCIe-based M.2 NVMe storage expansion, and compatibility with various other modules.
Argon Industria HMI 5C Specifications:
- Compatibility – Raspberry Pi 5
- Supported Display – Official Raspberry Pi Touch Display 2 (5-inch, 720 x 1280 resolution)
- Port access
- Display – HDMI (re-routed, full-size via internal PCB)
- Networking – Gigabit Ethernet RJ45 jack
- USB – 4x USB ports
- Expansion – GPIO header access
- Expansion
- Raspberry Pi HAT compatibility (disabled when cooling column installed)
- Optional PCIe M.2 NVMe expansion via add-on board
- IO PCB for port re-routing and cleaner cable management
- Power – IO PCB also reroutes the USB-C power input to the bottom edge
- Dimensions – TBD
- Enclosure
- Industrial-grade aluminum chassis for durability and heat dissipation
- A passive CPU cooling column transfers heat from the Pi 5 to the case body
- Mounting Options – VESA mount, panel mount, or desktop installation
What’s interesting is that the enclosure uses a physical cooling column together with its heavy aluminum body to act as a large passive heatsink for cooling the Raspberry Pi 5. However, installing this cooling column occupies the space that add-on boards would otherwise use, so if you plan to use a HAT, you’ll have to remove it and rely on an active cooler or low-profile heatsinks instead.
The company also mentions that the enclosure supports the Cytron Industrial IO HAT+ for connecting to automation and legacy equipment, and that it will be compatible with upcoming Argon Industrial Communication modules, which will turn the HMI into a central hub for connected systems.
From the Argon Industria HMI Assembly Guide, it’s clear that the company uses an I/O daughterboard to route all ports to a single edge of the enclosure for cleaner cable management. But a closer look shows the daughterboard is very similar to the Waveshare Pi5 Connector Adapter, which also means you can use the newer Connector Adapter (C) to add another M.2 2230/2242 NVMe SSD storage to the system.
The Argon Industria HMI 5C enclosure is available on the Argon40 store for $35.00, and you can purchase a complete kit on Cytron for $511 with a Raspberry Pi 5 16GB and the IO HAT+, or a case + 5-inch RPi Touch Display 2 for $93.25 If you own a 7-inch Raspberry Pi Touch Display 2, there’s the Argon Industria HMI 7C case instead from Argon or Cytron.
